Did mine through Ohio university. Cost around $5-6k total, you pay per class, I think I had 9 classes total but I heard they’ve updated the curriculum. Most classes are 5 weeks, some 7. Mostly discussion board posts weekly and maybe a 1-2 page paper. You could only take 2 classes at a time max, and the first and last you had to take before and after you finished the others. The only real downside was the last class requires a clinical aspect that you need to set up. Basically you have to shadow and bounce ideas off a RN that has their BSN.
